Manufactured from high-quality malleable iron, trimmed by grinding and filing before components are hand-forged together. Where required, individual pieces are drilled and tapped. The articles are then coated with a stove-baked paint before they are sealed with a heat-cured black powder coating. Moving parts are then tested and adjusted by hand to ensure free operation.

Made from completed DB articles. Most of the black finish is stripped off and the metal polished. The surface is then immediately sealed with two coats of a matte, weather-resistant sealer.

Manufactured from brass by the same method as malleable iron. Coated with a weather-resistant, three-component polyurethane coating. Brass articles may be finished as Oil-Rubbed or Dark BRS instead of a bright polished brass finish.

Same manufacturing method and coating as Solid Brass. Bronze articles may be finished as Oil-Rubbed or Dark BNZ instead of a bright polished bronze finish.

Black finish and rust deterrent are stripped from the article, then natural rust is generated on iron surfaces or natural rust powder is bonded to other metals. Finally, the article is finished with two coats of a weather-resistant, three-component polyurethane coating.

Made from completed DB articles. All of the black finish is stripped off and the bare malleable iron left unprotected or coated, as desired. This finish is usually requested to prepare an article for plating.
